主　　题：steelmaking slag leaching yield calcium content 

摘      要：In order to study calcium leaching behavior for the steelmaking slag,factors that influence the leaching yield have been *** results show that granularity of the slag,liquid to solid ratio（in short for L/S）,temperature and reaction time have a significant effect on the leaching *** optimal conditions for leaching are determined as follows：1） the granularity at 75 μm,L/S at 100,temperature at 60 ℃;2） the granularity at 75 μm,L/S at 50,temperature at 40 ℃.Finally,the optimal leaching yield under these conditions is about 15%
